Summary
Obot 0.21.1 through 0.24.1 Authorization Bypass via /mcp-connect-composite/ Route
Details

Obot 0.21.1 through 0.24.1 contains an authorization bypass vulnerability that allows authenticated users to reach MCP servers because the checkUI deny list omits the /mcp-connect-composite/ route. Basic-role users with a composite MCP ID can proxy requests through mcpGateway.Proxy to invoke tools on MCP servers restricted by Access Control Rules.
